You could do that, for sure.
Ooh, I have an idea! (You don't have to do it, I'm just throwing it out there). Have you ever read La Passe-Miroir? The English title is A Winter's Promise (which irritates me because it's nothing close to the meaning of the original title, but that's unrelated).
It has this little bit, maybe half a page long, before the first chapter, like a tiny mini-prologue. You could take the beginning of your story, the description of the mysterious "she" and the storm, and stick it before your first chapter. I'd probably cut it off before the descriptions of the kingdom and the Proficients/Non-Proficients, and just give the readers a little taste of what will happen later in the book to intrigue them. Like a little flash-forward. The rest it, about the kingdom, etc. can probably be moved to the new first chapter.
(Side note, but if you haven't read A Winter's Promise, you should. The writing is fantastic).
